A Data Parallel Algorithm for Seismic Raytracing

- Summary
- Metrics

Abstract

Dijkstra’s single-source shortest path algorithm has been applied in seismic tomography to determine paths of minimum travel time from all locations in a 3D earth model to sensors used in seismic experiments. An iterative data parallel algorithm is formulated for seismic tomography based on the Bellman-Ford-Moore (BFM) algorithm. Performance is demonstrated for OpenMP on multicore processors and OpenCL on GPUs.
